You can trial the maps too. Two weeks per module. One at time, two at time, all at a time, all consecutively. There are exceptions. The newest stuff, like the F4U, is not available for trial for a while. None of the RAZBAM stuff is available for sale or trial.
Remember to go into the options, special, specific aircraft, and turn off the auto rudder and takeoff assist if you want a better look at what the pilots of those aircraft dealt with.
